All right... I got to the point where I was moving into a second box full of level 54 pokemon (I'm not sure how I ended up with 54 as the goal level, but anyway), and finally decided last night that it was time to pick a team and beat the E4. So, since it's now my Hall of Fame team:

Awesome team. Everybody saw some action, and they all made me proud.
Then I put them back in the box (in the Row of Honor - the first row in the first box), completely changed the team around, and set out across Skyarrow Bridge. So my current team is Skarmory, Vaporeon, Espeon, Magnezone, Mamoswine and my newly evolved Leafeon...
